This course is designed to provide a full overview of computer networking. We’ll cover everything from the fundamentals of modern networking technologies and protocols to an overview of the cloud to practical applications and network troubleshooting.
By the end of this course, you’ll be able to:
● describe computer networks in terms of a five-layer model.
● understand all of the standard protocols involved with TCP/IP communications.
● grasp powerful network troubleshooting tools and techniques.
● learn network services like DNS and DHCP that help make computer networks run.
● understand cloud computing, everything as a service, and cloud storage.

I loved this course. When I had issues support was awesome sauce. I really enjoyed the puns this instructor used to keep you from going off in a daze. I really wish I would have found Coursera sooner.

Definitely teaches you the basic of networking that are needed to understand how it works as a whole. Would recommend anyone who is interested in learning about networking to enroll in this course.

The Transport and Application Layers

In the third week of this course, we'll explore the transport and application layers. By the end of this module, you'll be able to describe TCP ports and sockets, identify the different components of a TCP header, show the difference between connection-oriented and connectionless protocols, and explain how TCP is used to ensure data integrity.

The first three layers of our Network Model have helped us describe how individual nodes on a network can communicate with other nodes on either their own network or a remote one. But we haven't discussed how individual computer programs can communicate with each other. It's time to dive into this, because that's really the aim of computer networking. We network computers together, not just so they can send data to each other, but because we want programs running on those computers to be able to send data to each other. This is where the Transport and Application layers of our networking model come into play. In short, the Transport layer allows traffic to be directed to specific network applications. And the Application layer allows these applications to communicate in a way they understand. By the end of this module, you'll be able to describe TCP ports and sockets and identify the different components of a TCP header. You'll also be able to show the difference between connection oriented, and connection lists protocols, and explain how TCP is used to ensure data integrity. Are you ready to be transported to the next lesson? I hope so, because the Transport layer is up next. See you there.
